HOLDER.

Specification of Letters Patent.

Patented May 8, 1917.

Application filed June 17, 1916. Serial No. 104,294.

To all whom it may concern Be it known that I, REMMER H. SIETSEMA, a citizen of the United States, residing at Little Rock, in the county of Lyon and State of Iowa, have invented certain new and useful Improvements in Holders, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in holders and has relation more particularly to a device of this general character especially designed and adapted for use in connection with adhesive insect traps such as fly paper; and it is an object of the invention to provide a device of this general character whereby a sheet of paper of this general type may be effectively clamped to the holder,

It is also an object of the invention to pro- 6 vide a device of this general character having novel and improved means whereby the paper after being applied within the holder is protected in the event the holder should be turned over or otherwise assume an inoperative position.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved holder whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter more fully set forth.

The novel features of the invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, 1 will now proceed to describe the same with reference to the accompanying drawings, wherein Figure 1 is a view in perspective illustrating a holder constructed in accordance with an embodiment of my invention;

Fig. 2 is a fragmentary transverse sectional view taken through a longitudinal margin of the device as disclosed in Fig. 1 with the expansible member omitted;

Fig. 3 is a fragmentary view in perspective illustrating a slightly modified form of construction Fig. 4: is a fragmentary View in top plan illustrating a further embodiment of my invention as particularly relates to the clamp or wedge members; and

Fig. 5 is a fragmentary view in section illustrating a still further embodiment of my invention.

As disclosed in the accompanying drawings, 1 denotes a body plate of predetermined configuration preferably formed of sheet metal and rectangular in form and having its longitudinal margins returned, as at 2, to afford grooves substantially V- shaped in cross section which are adapted to receive the clamping or wedging members 3 also preferably V-shape in cross section and formed of a single length of material bent back upon itself throughout the entire length thereof.

The extremities of the members 3 have interposed therebetween the expansible members 4; which serve to initially maintain said members separated a distance greater than the transverse diameter of the plate 1 so that when the clamp or wedge members 3 are inserted within the grooves afforded by the returned portions or flanges 2,the sheet S will be effectively held upon the plate 1. When it is desired to remove a sheet S it is only necessary to retract the expansible members t a distance to unseat the wedge or clamping members 3 within the grooves.

As is particularly illustrated in Figs. 1 and 2, each of the expansible members t comprises a single length of wire of requisite gage having its apex portion coiled as at 5 to assure the requisite spring action and with the free extremities thereof suitably secured to the adjacent ends of the clamp or wedge members 3.

It is also to be observed that the expansible members 4: are disposed at right angles to the clamp or wedge members 3 and in a direction away from the plate when in applied position. By this arrangement it will be perceived that the members 4 serve as a means to prevent injury to the sheet S upon the plate 1 being turned over or otherwise assuming an inoperative position.

I also find it of advantage to provide an end portion. of the plate 1 with one or more openings 6 whereby the same may be sus pended or held in a desired location.

As illustrated in Fig. 1 the extremities of each of the members 4 are straight, while in Fig. 3 the extremities of the members 4 are provided with the inturned angular extensions 7 which are suitably secured as by solder, to the coacting clamp or wedge members 3.

In the form of invention illustrated in Fig. 4, the parts are substantially the same as has been hereinbefore set forth except that the expansible members 4: are disposed in substantially the same general direction as the wedge or clamp members 3 with the apices of said expansible members outermost. lVhile it is preferred that the clamp or Wedge members be substantially V-shape in cross section, it will be understood that good results can be obtained by having the same substantially U-shape in cross section as illustrated in Fig. 5 and in which event it is to be understood that the grooves of the plate will be of substantially the same configuration in cross section.

From the foregoing description, it is thought to be obvious that a holder constructed in accordance with my invention is of an extremely simple and comparatively inexpensive nature and is particularly Well adapted for use by reason of the convenience and facility with Which it may be assembled, and it will also be obvious that my invention is susceptible of some change and modification without material departure from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice, except as hereinafter claimed.

I claim:

1. A holder of the class described comprising spaced, parallel sheet engaging parts extending along the holder, a clamping member to co-act with each of said parts substantially throughout the length thereof, and means operatively connecting the clamping members to each other at their opposite ends and normally acting to urge the same to efiective position and clamp the sheet upon said parts.

2. A holder of the class described comprising opposed, parallel sheet engaging parts extending along the holder, a clamping member to co-act with each of said part-s substantially throughout the length thereof, and yieldable means operatively connecting said members to each other at their opposite ends and normally actingto urge the same to effective position and clamp the sheet upon said parts.

3. A holder of the class described comprising opposed, parallel sheet engaging parts extending along the holder, a clamping member to co-act with each of said parts substantially throughout the length thereof, and yieldable means operatively connecting said members to each other at their opposite ends and disposed in a plane at right angles to the plane of said members and normally acting to urge the same to effective position and clamp the sheet upon said parts.

4-. A holder of the class described comprising spaced sheet engaging parts, clamping members to co-act with said parts, each of said members consisting of a metal strip bent upon itself, and a yieldable connection between the corresponding ends of said clamping members fixed at its extremities between the opposed portions of the metal strips, said yieldable connections urging the clamping members toeffective position to clamp the sheet upon said parts.

A holder of the class described comprising a. sheet metal plate having its opposite marginal edges bent inwardly to afford longitudinal grooves, clamping members to co-act with the walls of said grooves, each of said members consisting of a metal strip longitudinally bent upon itself, and expansible elements connecting said clamping members to each other at their corresponding ends and having their extremities permanently fixed between the opposed portions of the metal strips, said elements urging the clamping members in relatively 0pposite directions and into operative engagement between the marginal edges of the plate.

6. A holder of the class described comprising a metal plate having its opposite marginal edges inwardly bent to afford substantially V-shaped grooves, clamping members each consisting of a metal strip bent on a longitudinal line upon itself, and a resilient wire rod connecting the corresponding ends of said clamping members and having its extremities permanently fixed between the opposed portions of the metal strips, said rods projecting in a plane at right angles to the plane of said members and nor mally acting to urge the members in relatively opposite directions toward the marginal edges of the plate to clamp a flexible sheet Within the grooves thereof.
